26 or die "Timed out!";
27
28 Executes $block with a timeout of $seconds. Returns the return
29 value of the $block if it completed within the timeout. If the
30 timeout is reached and the code is still running, it halts it and
31 returns undef.
32
33 NB: every $code_ref should return something defined, otherwise the
34 caller doesn't know if a timeout occurred.
35
36 Calls to do_with_timeout() can be nested. Any exceptions raised by
37 $block are propagated.
